Bill Cipher, an inter-dimensional being who had accidentally destroyed his home dimension and attempted to take over another universe. In multiple universes, he won but in one of them, he lost, twice. Now he has to face the facts, he will never take over that universe. So he has to find a dimension, a universe where he can find a planet that is easy to manipulate. No, not a planet, a country, a kingdom! And this kingdom in mind? Equestria.

Takes place after the events of “The Book of Bill” by Alex Hirsch.

My take on Death Battle's Bill Cipher VS Discord.
